..Gould's memory capacity was legendary. Both his mental and finger memory made it possible for him to reproduce and play music literature many years after his last practice and performance of the same. A famous illustration of this statement would be an event that occurred in 1970, when the renown Italian pianist, Arturo Benedetti Michelangeli, was unable to go through with his performance of Beethoven'sConcerto No.5, Emperor, in Toronto. Gould was given a telephone call on Thursday evening. The problem was explained, and he was asked to substitute for Michelangeli the next morning, on Friday, when the Toronto Symphony and the conductor, Karel Ancerl, were scheduled to work with Michelangeli. Gould's answer was affirmative and good-spirited. In the space of the next few night hours, Gould rehearsed the Concerto he had not touched in four years. The program was televised and, subsequently, aired on September 12, 1970. To everyone's amazement, Gould played Beethoven's Concerto in front of the camera flawlessly and by heart.

Appassionata.
Ludwig van Beethoven'sPiano Sonata No. 23 in F minor, Op. 57 (colloquially known as the Appassionata, meaning "passionate" in Italian) is among the three famous piano sonatas of his middle period (the others being the Waldstein, Op. 53 and Les Adieux, Op. 81a); it was composed during 1804 and 1805, and perhaps 1806, and was dedicated to CountFranz von Brunswick. The first edition was published in February 1807 in Vienna.
Unlike the early Sonata No. 8, Pathétique, the Appassionata was not named during the composer's lifetime, but was so labeled in 1838 by the publisher of a four-hand arrangement of the work.
One of his greatest and most technically challenging piano sonatas, the Appassionata was considered by Beethoven to be his most tempestuous piano sonata until the twenty-ninth piano sonata (known as the Hammerklavier).
Allegro assai
A sonata-allegro form in 12/8 time, the first movement progresses quickly through startling changes in tone and dynamics, and is characterized by an economic use of themes.
The main theme, in octaves, is quiet and ominous. It consists of a down-and-up arpeggio in dotted rhythm that cadences on the tonicized dominant, immediately repeated a semitone higher (in G♭). This use of the Neapolitan chord (e.g. the flattened supertonic) is an important structural element in the work, also being the basis of the main theme of the finale.
As in Beethoven'sWaldstein sonata, the coda is unusually long, containing quasi-improvisational arpeggios which span most of the early 19th-century piano's range. The choice of F minor becomes very clear when one realizes that this movement makes frequent use of the deep, dark tone of the lowest F1 on the piano, which was the lowest note available to Beethoven at the time.

Glenn Gould

Glenn Herbert Gould (25 September 1932–4 October 1982) was a Canadian pianist who became one of the best-known and most celebrated classical pianists of the 20th century. He was particularly renowned as an interpreter of the keyboard music of Johann Sebastian Bach. His playing was distinguished by remarkable technical proficiency and capacity to articulate the polyphonic texture of Bach's music.

Born in Bonn, then the capital of the Electorate of Cologne and part of the Holy Roman Empire, Beethoven displayed his musical talents at an early age and was taught by his father Johann van Beethoven and by composer and conductor Christian Gottlob Neefe. At the age of 21 he moved to Vienna, where he began studying composition with Joseph Haydn, and gained a reputation as a virtuoso pianist. He lived in Vienna until his death. By his late 20s his hearing began to deteriorate, and by the last decade of his life he was almost totally deaf. In 1811 he gave up conducting and performing in public but continued to compose; many of his most admired works come from these last 15 years of his life.

Surname

A surname or family name is a name added to a given name. In many cases, a surname is a family name and many dictionaries define "surname" as a synonym of "family name". In the western hemisphere, it is commonly synonymous with last name because it is usually placed at the end of a person's given name.

The style of having both a family name (surname) and a given name (forename) is far from universal. In many countries, it is common for ordinary people to have only one name or mononym.

The concept of a "surname" is a relatively recent historical development, evolving from a medieval naming practice called a "byname". Based on an individual's occupation or area of residence, a byname would be used in situations where more than one person had the same name.
